DETAILED DESCRIPTION

Reference is now made to several views of the drawings inFIGS. 1-15 to show an embodiment of the combative helmet of the present invention. The basic helmet construction is shown at10 and a visor is shown at12. Typically, part of the helmet construction includes apadded rim13 illustrated inFIG. 1.FIG. 1 also illustrates the slide assembly at20. Although not illustrated in the drawings, there is a like mirrorimage slide assembly20 on the opposite side of the visor so that the same pivoting action can occur on both sides of the visor.

The fragmentary perspective view ofFIG. 3 illustrates theslide assembly20 in what may be considered a locked position. Reference can also now be made toFIG. 12 which shows the basic components of theslide assembly20. Thisslide assembly20 includes amain base plate22 that is secured to the helmet. This is illustrated inFIG. 3 secured to awall14 of thehelmet10. Thebase plate22 has end internally threadedholes23, asawtooth interlock surface26, ahole25 for accommodatingscrew50 and a tang27 (see alsoFIGS. 4 and 5). The slide assembly also includes theslide plate30 which includes anelongated slot31 for receiving thescrew50 and asawtooth surface32. Theslide plate30 is also provided with internally threadedholes34. InFIG. 12 a third main component is thepivot plate40. Thescrew50 is secured to thepivot plate40 by means of apin54. Thescrew50 has a threaded end at55 and ahead51 with ahole52 extending therethrough. Thepin54 is for accommodation in a set ofholes46 inrespective arms44 of thepivot plate40. Thepin54 is positioned through theholes46 and provides a pivot point for thepin50.

FIGS. 4 and 5 illustratemain base plate22 secured to thehelmet wall14. This securing of thebase plate22 firmly holds the base plate against thewall14 by means ofscrews24.FIGS. 4 and 5 also illustrate thescrews36 used for attachment of theslide plate30 with thevisor12. As also illustrated inFIGS. 4, 5 and 12, there is another throughhole25 that accommodates thescrew50 that is free-floating within thehole25. Thehole25 may be un-threaded. Thebase plate22 also includes anend tang27. InFIG. 4 thisend tang27 is shown engaged by thelatch42 at theend hook43.FIG. 4 shows the engaged position, whileFIG. 5 illustrates thelatch42 having been disengaged from thetang27. This enables a pivoting of thepivot plate40. This pivoting is illustrated in an initial position inFIG. 5, and is generally about the axis of thepin50.

Reference is now made toFIGS. 6-10 which show the following operation that enables the visor to be moved forwardly and pivoted upwardly. In this regard,FIGS. 6 and 7 illustrate a relationship betweenbase plate22 and theslide plate30 that is interlocked. In that regard, therespective sawtooth surfaces26 and32 are shown interlocked inFIG. 7.FIG. 7 also illustrates byarrow70 the pivoting of thepivot plate40 to a position substantially orthogonal to thebase plate22. In the position ofFIG. 7, thescrew50 is engaged within thehole25 of thebase plate22.

Reference may now be made to the cross-sectional view ofFIG. 8 which illustrates a de-coupling between thesawtooth surfaces26 and32 to enable a sliding action of theslide plate30. This occurs by virtue of the wearer of the helmet moving the slide plate away from the base plate, such as in the direction ofarrows72 as illustrated inFIG. 8. This sliding motion occurs while thepin50 is still maintained in thehole25 of thebase plate22.FIG. 9 now illustrates the next step which is the sliding of theslide plate30 in the direction ofarrow74. This is enabled by virtue of theelongated slot31 in theslide plate30 that enables the slide plate to move to the position ofFIG. 9 while still engaged with thepin50. Finally, in the fragmentary enlarged perspective view ofFIG. 10, thearrow76 illustrates a pivoting of the visor to an upward position. In the position ofFIG. 10, theend47 of thepivot plate40 atarms44 is preferably flat so that thepivot plate40 is essentially maintained in that position while still allowing a pivoting action in the direction ofarrow76.FIG. 11 also illustrates this pivoting action, illustrating theslide plate30 and thepivot plate40.

Reference is also now made to respective side elevation views shown inFIGS. 13-15. The purpose of these views is to illustrate the manner in which thevisor12 can easily be moved forwardly and then pivoted upwardly so as to clear thecushion13 on thehelmet10. In this regard,FIG. 13 illustrates avisor wall15. It is noted that in the closed locked position of the visor, thiswall15 is under thecushion13 and thus would not be able to be moved upwardly. The next side elevation view ofFIG. 14 illustrates theslide member30 being moved in the direction ofarrow80. In that position it can be seen that thevisor wall15 is clear of thearcuate cushion member13. Finally, in the side elevation view ofFIG. 15, thearrow82 illustrates a pivoting or tilting of thevisor12 to an open position. The pivoting ofFIG. 15 is essentially about the axis of thescrew50.

It is also understood that the actions described herein can readily be reversed so that the visor can be moved from the open position as illustrated inFIG. 15 to a downward position as illustrated inFIG. 14 and from there the slide member is slid in the direction opposite to thearrow80 inFIG. 14. The sawtooth surfaces26 and32 can then be engaged as illustrated in the cross-sectional view ofFIG. 7 and thepivot plate40 is then pivoted to a locked position as illustrated in the cross-sectional view ofFIG. 4.

As indicated previously, there is aslide assembly20 on each side of the helmet and the actions that are described herein are meant to apply equally to both the slide assemblies so that the action taken is in concert, whether opening or closing the visor.

Having now described a limited number of embodiments of the present invention, it should now be apparent to those skilled in the art that numerous other embodiments and modifications thereof are contemplated as falling within the scope of the present invention, as defined by the appended claims.
